    For more then a week the installation on an essential security
    ..NET-FrameWork-update for version 1.1 fails; error 0x643.

    Looking over Microsoft website I tried two things:
    - rename the Software-Distribution folder so that Windows created a new one;
    - I removed all installed .NET-FW versions (1.1, 2.0, 3.0 and 3.5) by
    Control Panel/Software and then the remnants by WindowsInstallCleanup
    application.
    Then I had to run Windows Update and it wanted to install .NET-FW 3.5 SP1
    with .NET-FW 3.5 Family-Update x86.
    Installation failed again; Error 0x80070645.

    So, what to do now? Could there be a missing file?
    I cleaned up my pc and ran ccleaner two weeks ago.


    Error 0x643

    Error 0x80070645

  3. 1. Before doing anything else, write down the .NET Framework versions which
    are already installed:

    How to determine which versions of the .NET Framework are installed and
    whether service packs have been applied


    2. Now see Resolution Method 2 in...

    When you try to install an update for the .NET Framework 1.0, 1.1, 2.0, 3.0,
    or 3.5, you may receive Windows Update error code "0x643" or Windows
    Installer error code "1603" (ignore the title, if need be)


    After running the appropriate eeded tool, (re)install all .NET Framework
    versions manually using the download links on the page then run Windows
    Update manually to install security updates for same.

    NB: If you've removed .NET Framework 3.5 SP1, reinstalling it will also
    install .Net Framework 2.0 SP2 and 3.0 SP2.

    IMPORTANT! => If you've removed .NET Framework 3.5 SP1, reinstall your .NET
    Framework versions in the following order:

    1. .Net Framework 3.5 SP1, then...
    2. .Net Framework 1.1, then...
    3. .Net Framework 1.1 SP1

    NB: KB923100 references this page:
    . Please read
    ALL of it as well as the related page
    before using the .NET
    Framework Cleanup Tool.
